AMD Threadripper 3990X : World’s First 64-Core HEDT CPU!

The AMD Ryzen Threadripper 3990X – the world’s first 64-core, 128-thread HEDT processor is finally here!

Here are the full details on this crazy 64-core HEDT processor – the official tech briefing, the official promo video, specifications, price and more!


The 3rd Gen AMD Ryzen Threadripper Processor Family

The AMD Ryzen Threadripper 3990X is the world’s first 64-core HEDT processor, headlining the 3rd Gen Threadripper family, which now looks like this :

  • Ryzen Threadripper 3990X : 64C / 128T, 2.9GHz / 4.3GHz, 288 MB cache
  • Ryzen Threadripper 3970X : 32C / 64T, 3.7GHz / 4.5GHz, 144 MB cache
  • Ryzen Threadripper 3960X : 24C / 48T, 3.8GHz / 4.5GHz, 140 MB cache

Like the 3rd Gen AMD Ryzen processors, the AMD Ryzen Threadripper 3990X processor is based on the new Zen 2 architecture with the chiplet design approach.

The CPU dies are fabricated on the 7 nm process technology, while the I/O die is fabricated on the 12 nm process technology.

There is no better person to tell you how awesome it is to have 64-cores of processing power in the new Ryzen Threadripper 3990X than Robert Hallock, AMD Senior Technical Marketing Manager.


New Socket sTRX4 + AMD TRX40 Chipset

The AMD Ryzen Threadripper 3990X requires a AMD TRX40 motherboard with a new sTRX4 processor socket. However, you will still be able to use existing Threadripper coolers.

The processor comes with 64 PCIe 4.0 lanes, of which 56 are available for use. The AMD TRX40 chipset adds another 24 PCIe 4.0 lanes, with 16 free lanes.

In total, the new Socket sTRX4 and TRX40 chipset will give you 72 free PCIe 4.0 lanes to use, compared to just 56 free PCIe 3.0 lanes in previous generations.

In addition, the new AMD TRX40 chipset communicates with the 3rd Gen Threadripper using a PCIe 4.0 x8 link. This gives it 4X more bandwidth than the PCIe 3.0 x4 link used in the first two generations.

AMD Ryzen Threadripper 3990X Performance

In this video, Robert shows how the new 64-core Threadripper 3990X and even the 32-core Threadripper 3970X handily beat the Intel Xeon W-3275 processor – their best single-chip processor.


AMD Ryzen Threadripper 3990X Price + Availability

The 64-core AMD Ryzen Threadripper 3990X is priced at a princely RM16,999 / S$5,988 / US$3,990, which is almost double that of the Threadripper 3970X!

You can grab one from AMD or their retail partners starting from 7 February 2020 onwards, and start making your own Terminator : Dark Fate movie! 😀
